How close are we to electric aircraft?

Some companies are looking at jet aircraft powered by electricity. For example, Wright Electric is working on a 100-seat fully-electric regional jet that could take off starting in 2026. The Wright Spirit is a conversion of the BAe 146 regional jet, destined for one-hour flights.

Hybrid and all-electric planes
Experts believe hybrid and fully battery-powered planes, which offer less range than conventional aircraft, will begin to dominate the short-haul flight sector by 2030, becoming the go-to craft for flights under three hours.

There is a way out and it's called an electric jet-engine. In short, instead of generating the hot exhaust through a chemical combustion process (like a typical jet-engine), the exhaust gas comes from a plasma source powered by electricity.

Some airplanes have a ram air turbine that is lowered when electrical power is lost to provide a backup to power a hydraulic pump and limited electrical generator. As for the loss of the engines, all airplanes can glide to a landing.

According to Drela, today's airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)

In the current estimate for 2021-2040, over the next two decades 612,000 new pilots will be required worldwide, with 130,000 of these in North America, primarily the U.S.. Expectations are similar for other staff in the aviation industry such as mechanics and cabin crew, as the whole market expands.

Yes, it is possible to build a steam powered aeroplane. The first sucessful powered, heavier than air, flying machine was steam powered, built by Henson and Stringfellow in 1847. Several later designers also built sucessful models.
